1.1 This classification covers and is designed to standardize and consolidate the terminology, nomenclature, and classification of metalworking fluids and related materials.

1.2 Metalworking fluids includes both metal removal and forming fluids. These are the coolants and lubricants associated with both types of processes.

1.3 This classification implies no evaluation of product quality or suitability for a given metalworking operation.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Metalworking may be divided into two general types of processes, metal deformation (such as rolling) and metal removal (such as grinding or cutting). This classification lists the various types of fluid and non-fluid materials used to directly provide cooling and lubrication in both types of metalworking processes. It is intended for use by those in metalworking or related industries who want to differentiate these materials. It is up to the user of this classification to determine the relevance of the items listed with respect to their application.
